New Britain is a city in Hartford County, Connecticut, United States. It is located approximately 9 miles (14 km) southwest of Hartford. The city is part of the Capitol Planning Region. According to 2020 Census, the population of the city is 74,135.

Among the southernmost of the communities encompassed within the Hartford-Springfield Knowledge Corridor metropolitan region, New Britain is home to Central Connecticut State University and Charter Oak State College. The city was noted for its industry during the 19th and early 20th centuries, and notable sites listed on the National Register of Historic Places include Walnut Hill Park, developed by the landscape architect Frederick Law Olmsted and Downtown New Britain.

The city's official nickname is the "Hardware City" because of its history as a manufacturing center and as the headquarters of Stanley Black & Decker. Because of its large Polish population, the city is often playfully referred to as "New Britski."

New Britain was settled in 1687 and incorporated as a new parish as the New Britain Society in 1754. Chartered in 1850 as a township and in 1871 as a city, New Britain had separated from the nearby towns of Farmington and Berlin, Connecticut. A consolidation charter was adopted in 1905.

During the early part of the 20th century, New Britain was known as the "Hardware Capital of the World", as well as "Hardware City". Major manufacturers, such as The Stanley Works, the P&F Corbin Company (later Corbin Locks), Landers, Frary & Clark (LF&C) and North & Judd, were headquartered in the city.

In 1843 Frederick Trent Stanley established Stanley's Bolt Manufactory in New Britain to make door bolts and other wrought-iron hardware. In 1857 his cousin Henry Stanley founded The Stanley Rule and Level Company in the city. Planes invented by Leonard Bailey and manufactured by the Stanley Rule and Level Company, known as "Stanley/Bailey" planes, were prized by woodworkers of the late 19th and early 20th centuries and remain popular among wood craftsmen today. The two companies merged in 1920, and the Stanley Rule and Level Company became the Hand Tools Division of Stanley Works.

The wire coat hanger was invented in 1869 by O. A. North of New Britain. In 1895, the basketball technique of dribbling was developed at the New Britain YMCA. In 1938, New Britain High School competed in the high school football national championship game in Baton Rouge, Louisiana. 1954 saw the development of racquetball, also at the YMCA.

The heads of the fire and police departments and seven other municipal employees were arrested as part of a corruption scandal in the 1970s.

New Britain's motto, Industria implet alveare et melle fruitur—translated from Latin—means "Industry fills the hive and enjoys the honey." This phrase was coined by Elihu Burritt, a 19th-century New Britain resident, diplomat, philanthropist and social activist.

In 2007 it was reported that the Latin word for "honey" in the motto had been a typo for decades; it should be melle, but it had long been misspelled as mele. Former mayor William McNamara, who unsuccessfully tried to fix it during his term, suggested "to either fix the spelling immediately" or "switch to the English version of the motto." As controversy arose from the matter, the word was superseded with the correct spelling, melle.

According to the United States Census Bureau, the city has a total area of 13.4 square miles (34.7 km), of which 13.3 square miles (34.6 km) is land and 0.1 square mile (0.2 km) (0.52%) is water.

New Britain's terrain is mostly made up of gentle, rolling hills and young Connecticut forest. The many parks are populated with trees, and in small, undeveloped areas, there are also brushy woods. New Britain's streets also have many trees lining the sides of the roads. Many front yards in the northern half of the city have at least one tree. One or two streams flow through New Britain, undisturbed by the development.

New Britain has the largest Polish population of any city in Connecticut, and by 1930 a quarter of the city was ethnically Polish. Also referred to as "Little Poland", the city's Broad Street neighborhood has been home to a considerable number of Polish businesses and families since 1890. On September 23, 2008, through the urging of the Polonia Business Association, the New Britain City Council unanimously passed a resolution officially designating New Britain's Broad Street area as "Little Poland." In recent years, the Polish community has been credited with revitalizing the area both culturally and economically. Media is served by three Polish language newspapers and a television station, and many businesses and civil agencies are bilingual. The post office branch in Little Poland is the only one in the nation with the word "post" written in Polish to welcome visitors. Each year, a Little Poland festival is held on a Sunday in the spring.

Notable visitors to the Polish district have included Presidents Richard Nixon and Ronald Reagan on July 8, 1987. In 1969, as then-Cardinal Karol Wojtyła, the future Pope John Paul II gave a mass at Sacred Heart Church. A statue was erected in his honor in 2007. Dubbed the city's "Polish heart" by The Boston Globe, Little Poland caught the attention of Polish Ambassador to the US Ryszard Schnepf, who toured the area with US Senators Chris Murphy and Richard Blumenthal, US Congresswoman Elizabeth Esty, as well as several members of the Polish Sejm. An honorary Polish consulate was established in March 2017. The first of its kind in Connecticut, it was established by Polish diplomat to the United States Piotr Wilczek.

In September 2019, Polish President Andrzej Duda became the first head of state to visit New Britain when he addressed thousands in Walnut Hill Park prior to traveling to New York City for the United Nations General Assembly. Duda was joined by a variety of Connecticut politicians, including Governor Ned Lamont, U.S. Representative Jahana Hayes and Senators Chris Murphy and Richard Blumenthal.

Natives of New Britain have a fairly unmarked Connecticut accent, though there is some local perception of a distinct accent, popularly attributed to the Polish-American community, such as the use of a glottal stop in place of /t/ before syllabic /l/: in other words, in words like cattle and bottle. The short "a" vowel /æ/ as in TRAP may be raised to [ɛə] for some speakers in Connecticut, including New Britain, though this feature appears to be declining among younger residents.
